AI Technical Summary

Technical Problem

The simple molds used in existing automatic stamping equipment require constant lubrication to prevent jamming and burr formation, resulting in environmental pollution and high production costs, while product quality remains unstable.

Method used

Design a stamping die with different clearance structures for the upper and lower dies. The clearance between the punch and the upper die is 10%~15%, and the clearance between the lower die and the punch is 20%~30%. Combine guide grooves and positioning holes to ensure smooth operation of the die and avoid the use of lubricating oil.

Benefits of technology

Reduce mold jamming and burr problems, improve product quality and production efficiency, avoid lubricant pollution and costs, and ensure the improvement of product quality and production efficiency.

Abstract

This utility model discloses a stamping die that reduces the occurrence of abnormalities such as die jamming or burrs during the operation of reinforcing film without the need for lubricating oil, thereby improving product quality and reducing quality risks. The stamping die, used for stamping reinforcing film, includes an upper die, a lower die, and a punch. The lower die is used to press the reinforcing film. The upper die and the lower die are detachably connected, and both are provided with a coaxial first through hole and a second through hole. The punch is coaxially inserted into the first through hole and the second through hole from top to bottom. Based on the material thickness of the reinforcing film, the gap between the punch and the first through hole is set to 10%~15% of the material thickness, and the gap between the punch and the second through hole is set to 20%~30% of the material thickness.
